[Plugin: Better WordPress Minify] Idea about priority

Ok, try Tippy http://ww.wp.xz.cn/extend/plugins/tippy/ lovely plugin.

It works like this out of the box:
1. 1 JS and 1 CSS file in head
2. Init snippet based on settings below them, and especially JS file!

With Better Minify this order is kept if nothing is touched but just moving “Tippy” to footer will render snippet useless as it depends on main file to be loaded before.

This might be obvious but lets say I do it manually like this

add_filter('bwp_minify_allowed_scripts', 'my_allowed_scripts');
function my_allowed_scripts() {
   return array(
   'Tippy'                // manually placed in footer
    );
   return;
}

And since I know snippet from plugin now wont work I move that too:

/* - [ TIPPY FIX ] - */
remove_action('wp_head', 'tippy_load_settings');
add_action('wp_footer', 'tippy_load_settings_new', 120); // 120 so it comes after BWP
function tippy_load_settings_new() {
	if (get_option('tippy_fadeTip', 'fade') == "fade")
	{
		$tippyFadeRate = 300;
	} else {
		$tippyFadeRate = 0;
	}
	echo '
		<script type="text/javascript">
			Tippy.initialize({
blah, blah
			});
		</script>
	';
}

Then it will STILL come before BWP bundle because you fire that off with a priority of 100, hence the added 120.

From class-bwp-minify.php

add_action('wp_footer', array($this, 'print_footer_scripts'), 100);

So that 100 number could be nifty to manipulate 🙂 More so because not all plugins allow this fiddling so not really anything to do other than changing number manually.

Or is there any action hook that will always come after “wp_footer”?

Not worlds biggest problem and may be nothing to do but if you have mentioned how a JS file can be tied to initialization snippets in FAQ I think you should. If not BWP will be blamed, that is guranteed 🙂

Yes it does work as order of what plugin expect is kept.

I was just thinking that the fact plugins can add initialization snippets all over the place might not be obvious to everyone. And both your plugin and users might break that and render output crap.

This is really obvious if source code is checked before fiddling – and we all to that… Your plugin make it clear enqueue´ing is all that counts and hence nothing can break, or should not, but you cant control what plugin spit out. So to cover your butt and may be warn a bit this might be relevant for a FAQ or sticky.

Btw, I see you will add feature for showing handles. Up to now I have used a snippet from WPEngineer, tuned by Stackoverflow and shined up by me – I added headlines and line breaks, heh. Links in code. Try check Background Manager plugin http://ww.wp.xz.cn/extend/plugins/background-manager/ for why this can stop tears. Nearly broke me. Usually easy enough to find those handles though, still nifty.

I have some respect for this minifying stuff. Why I prefer to do most manually and so I need handles, lots!

Also I have some doubts about minifying other file than those used on all pages. Your plugin respects conditional powers but that also means a site can get loads and loads of minifed “sets”. Good for caching = nope. Like starting over with a new unique bundle, again and again. In theory each page could have own set of JS and CSS. Feature not a bug? I need to think more but for now I prefer 1 static set of JS and 1 static set of CSS – selected by me. Only way is manual and know-how of how plugin works.
